Codeigniter: How to get resized image path? - php

Question

I am using default library of codeigniter to resize my image to get different thumbs. I have refer to Documentation of codeigniter for this.
My images gets resize fine. Now, I want to store resized image path in database. For that I checked library file and other details as well but not found a way to get resized image path.
Please check my code
protected function createThumbs($params)
{
if( !is_dir($params['targetPath']) ) {
mkdir($params['targetPath'], 0777, TRUE);
}
$tConfig['image_library'] = 'gd2';
$tConfig['source_image'] = $params['sourcePath'];
$tConfig['new_image'] = $params['targetPath'];
$tConfig['create_thumb'] = TRUE;
$tConfig['maintain_ratio'] = TRUE;
$tConfig['width'] = $params['width'];
$tConfig['height'] = $params['height'];
$this->load->library('image_lib', $tConfig);
if (!$this->image_lib->resize()) {
echo $this->image_lib->display_errors();
}
// clear //
$this->image_lib->clear();
}
Does anyone knows how to get it?

Answer 1

Try
protected function createThumbs($params)
{
if( !is_dir($params['targetPath']) ) {
mkdir($params['targetPath'], 0777, TRUE);
}
$tConfig['image_library'] = 'gd2';
$tConfig['source_image'] = $params['sourcePath'];
$tConfig['new_image'] = $params['targetPath'];
$tConfig['create_thumb'] = TRUE;
$tConfig['maintain_ratio'] = TRUE;
$tConfig['width'] = $params['width'];
$tConfig['height'] = $params['height'];
$this->load->library('image_lib', $tConfig);
if (!$this->image_lib->resize()) {
echo $this->image_lib->display_errors();
}
// clear
$this->image_lib->clear();
#return
$file_info = pathinfo($tConfig['new_image']);
return $file_info['dirname'].'/'.$file_info['filename'].'_thumb.'.$file_info['extension'];
}

Your thumb file will be called with _thumb at the end of file name.
For example if your file is: image.jpg your resized thumb will be called image_thumb.jpg

public function addUserImages()
{
$image = preg_replace("/\s+/", "_", $_FILES['user_image']['name']);
$config['upload_path'] = "./Images/ProfileImages/";
$config['allowed_types'] = "gif|jpg|png|jpeg|JPG|JPEG|PNG|GIF";
$config['file_name'] = $image;
$this->load->library('upload',$config);
if($this->upload->do_upload("user_image")==false)
{
$error = array('error' => $this->upload->display_errors());
echo $error['error'];
return $error->error;
}
else
{
$data = $this->upload->data();
$newImage = $data['file_name'];
$config['image_library'] = 'gd2';
$config['source_image'] = './Images/ProfileImages/'.$newImage;
$config['new_image'] = './Images/ProfileImages/small_'.$newImage;
$config['create_thumb'] = FALSE;
$config['maintain_ratio'] = TRUE;
$config['quality'] = '100';
$config['width'] = 250;
$config['height'] = 250;
$this->image_lib->clear();
$this->image_lib->initialize($config);
$this->load->library('image_lib', $config);
if(!$this->image_lib->resize())
{
return $this->image_lib->display_errors();
}
else {
$newImage = "small_".$newImage;
}
}
}
